I listened to a podcast recently by Sam Harris.

 

https://samharris.org/podcasts/108702/

 

As some of you may know arguments might be sound but that does not mean they prove anything to anyone.    Why?  Because people might not believe the premises.   I blogged about the difference between a proof and sound argument here:

 

https://trueandreasonable.co/2014/01/11/extra-extra-read-all-about-it-gods-existence-proven/

 

The limitations on these premises presents the questions what are our ultimate goals or beliefs?  This was somewhat explored in that podcast starting around 50 minutes in.   Rebecca Goldstein I think correctly identifies some beliefs that we can’t give up without becoming incoherent – such as belief in the rules of logic.  But beyond that what fundamental beliefs would she hold?

 

She mentions belief in an external world and the laws of nature.   That was interesting to me because I have considered that one myself and rejected as not as important as the belief that a rational person can reliably find out what I am supposed to do in life.    I want to explore why I think that here.

 

They also mentioned belief in moral realism as one that is fairly fundamental.   I think this sort of belief is what religious people will often adopt.  I think non-religious people will often try to reduce the importance of morality in forming our beliefs.  I think that is error.

There is a motivational aspect as to how we shape our beliefs and consciences.     I would offer two noble goals in what we want our beliefs to be:

1) People want to believe what is true

2) People want to believe things that lead them to do the right thing

Both of these are noble motivations.  And we obviously should try to form our beliefs with both of these in mind.  But what if certain beliefs lead you to the conclusion there is no right way to act?  That is certain beliefs lead you to believe what is wrong is not wrong because nothing is wrong?  Does a rational person have a good reason to reject that belief?   I think they do.

Now that might violate the first noble motivation.  But let’s think about that motivation just a bit and I think we will see it really is subservient to the second.

The idea that we are here to fill our heads with true beliefs and expunge false beliefs is odd.  If I just tried to memorize phone books few people would say that was really a good way to fill my head, or spend my time, even if I could fill my head with billions of true beliefs that way.    We all understand that knowing certain facts are more important than knowing others.  Just like some false beliefs are more problematic than other false beliefs.

 

But why?  Believing any true fact seems to fit the first noble purpose.   If it is a known fact then it has the quality of being true just as much as any other fact.   So why is it that truly believing some facts are more important, and why does it seem correctly believing other facts is extremely unimportant?   To the extent all the beliefs accord with reality, they are all true, and it is not as though some are “truer” than others.   So it is not the extent of “truthiness” that explains this.

I think ultimately the answer is that believing some facts leads us to live a good life and some falsehoods lead us to a bad life.   And I think this shows the second purpose is naturally more important.

What about some beliefs about morals being more important than other beliefs about morals?   Someone may view it as immoral to hunt deer.  The same person might also think it is immoral to round people up and kill them as was done in Poland at various times.   We do not treat the belief about hunting deer as important as the belief about killing people.  What explains this?  Again the person might believe both are immoral.  But the difference is the latter is more immoral.  So it is still the morality of the issue that makes us view the second belief as more important.  This I believe fairly clearly shows that morality is the more important goal that we want from our beliefs.

 

I think religious people tend to know this truth.  Certain atheists sometimes seem to miss it.  But then after they discuss their science, they tend to drift over to issues of morality and what we should be doing.   Science is great and it answers many interesting questions.  But having true beliefs about “what is” in the observable scientific realm, is not as important as knowing what we should do.  It is forever stuck with a supporting role to the star philosophical/religious question of what we should do.

 

 

The Conjunction Fallacy and the Burden of Proof

11 Thursday Jan 2018

As you know I think the philosophical burden of proof is a notion harmful to clear thinking.  My first post about it was here.  And here is a blog from someone who thinks very much the same way.  Here I will try to score some further points by undercutting common arguments used to support the view that having a burden of proof is helpful.

 

But first some background, what is the conjunction fallacy? Consider this example from Amos Tversky and Daniel Kahneman copied from Wikipedia:
“Linda is 31 years old, single, outspoken, and very bright. She majored in philosophy. As a student, she was deeply concerned with issues of discrimination and social justice, and also participated in anti-nuclear demonstrations.

Which is more probable?

1) Linda is a bank teller.
2) Linda is a bank teller and is active in the feminist movement.”

If you thought 2 was more probable, then you committed this fallacy.  It is a formal fallacy.  And it basically says that the probability of A+B will always lower or equal than the probability of A. As we add conditions the probability can only go down never up.

Why is this tricky to some people? (apparently most people chose option 2) Given the description of Linda many people might think she sounds like a feminist. Moreover, she does not sound like a bank teller. So the first option seems to only have what people think is unlikely.  Even though second option has what seems unlikely it also has what seem likely too. So the second option may seem preferable. But mathematically the second option will never be more likely than the first, because every time the second option holds true the first does as well.

When we add details to a claim the probability tends to drop. The probability that I am in front of my computer now, is greater than the probability that I am now in front of my computer wearing a shirt, which is greater then the probability that I am now in front of my computer wearing a brown shirt. This is just how logic works.  I think many of us know this and build this into our understanding of the world. So what does this have to do with the burden of proof?

If you go to youtube and type in burden of proof the first video to come up will be this one:

Listen to the first 20 seconds.
What is happening?  Well if you notice the person is not just asking whether “something” exists “in space” that we don’t have evidence of and whether we should believe that. Which I tend to think is true. But how would that help his case for “the burden of proof”? Of course it wouldn’t.

So he doesn’t just ask whether a general thing exists.   Instead he gets absurdly detailed with his description.  It is not something we don’t know about somewhere in space but under the surface of Pluto! And it is not just “something” its not even just some form of life, but a walrus. And of course even that is not enough. It is a “tiny” “were” walrus. But not only that it is a “psychic” tiny “wer”walrus. But no only that it is a tiny psychic werewalrus that “sends them psychic messages.” But not only that the messages come “every midnight.” And not only that but it does this while juggling skulls…..

 

Ok. So by now if you understand the conjunction fallacy  then you will know that amount of detail alone will drastically drive down the probability. There is no need to appeal any “burden of proof” to not believe in this creature. The probability is naturally driven down just by understanding the fallacy of conjunction.

It’s amazing that this video received 13,000 likes when it is really just an obvious play on this formal fallacy. Now if you are like me you will see this quite often from atheists. The other day when I said there is no philosophical burden of proof I was asked whether I believe “that there is an imperceptible penguin named “Percival” standing right across the room from me, wearing his imperceptible tuxedo and his imperceptible monocle and his imperceptible derby hat, holding his imperceptible pocket-watch.”

Now I want to point out that the proponents of a burden of proof who use these examples are not themselves committing the conjunction fallacy. But rather they just seem oblivious to its logic. It is the logic that makes the conjunction fallacy a formal fallacy that makes the probability of their examples quite low. So when you see these examples the response is not that they are committing a fallacy. Rather the response is more like yes the conjunction fallacy is indeed a fallacy so the probability of your extremely detailed scenario is low.

If you express doubts about “the philosophical burden of proof” you can expect this sort of thing. They won’t ask whether you can believe there is something somewhere we do not have evidence for. No, they will not even ask whether there is some species of life we have no evidence of yet. Rather they will ask about a particular horse that we have no evidence of. But not just a horse, but a horned horse, but not just a horned horse, but a horned horse with exactly one straight long horn coming out of its head. And often even that won’t be enough the horned horse will have to be pink.

And you might respond explaining this fallacy and ask them whether they believe there is something somewhere he/she does not yet have evidence of. I certainly believe there are things that exist that I have no evidence of. For example there very well may be a particular cricket in the southwest United States that I have no evidence of.

Which brings me to another point here. There is more than just the conjunction fallacy at work here. There are also background beliefs. There are probably crickets in the southwest United States. But when and how did a walrus get to Pluto? (forget the whole juggling psychic were bit)

Perhaps the classic example of this sort of argument is Russel’s Teapot. Russel said:
“ … nobody can prove that there is not between the Earth and Mars a china teapot revolving in an elliptical orbit, but nobody thinks this sufficiently likely to be taken into account in practice. I think the Christian God just as unlikely.”

So again, its not just something in space we don’t have evidence of.  It is something between the Earth and Mars and revolving in an elliptical orbit. It is not just something but a piece of China. And it is not just China but a China teapot. So we can see the logic of  conjunction fallacy at work reducing the probability.

But we also have background beliefs and evidence at work as well. Plantinga wrote:
“Clearly we have a great deal of evidence against teapotism. For example, as far as we know, the only way a teapot could have gotten into orbit around the sun would be if some country with sufficiently developed space-shot capabilities had shot this pot into orbit. No country with such capabilities is sufficiently frivolous to waste its resources by trying to send a teapot into orbit. Furthermore, if some country had done so, it would have been all over the news; we would certainly have heard about it. But we haven’t. And so on. There is plenty of evidence against teapotism.”

Another example might be if I say if we randomly pick a house in a New York suburb will there be three black horses in the Garage? You might say no. One reason would be conjunction fallacy. But also you would have back ground beliefs about what suburban houses likely have in their garage. If I asked does that house have light fixtures in it, well then you might say yes.

So Plantinga brings up evidence. And I think that may be a good way to describe what he is doing. But sometimes there are things that just don’t accord with our background beliefs. Now maybe these background beliefs are rational maybe they are not. Sometimes it may be difficult to completely understand or articulate why a certain claim seems true or untrue. Is there something beyond the known universe? In any case we have far more beliefs than we may even consciously realize.

For example, I never realized I believe plaid cats do not exist until last month. But I suppose I always believed it. (that is I was inclined to act in a way that accorded with the statement “there are no plaid cats”) This may be a sad fact of this kluge we call our brains. But it does not justify erecting some imagined burden of proof.  That is just piling error on top of error. When we consider 1) our background beliefs, 2) evidence and 3) the logic of the conjunction fallacy there is no reason to appeal to the burden of proof.

If you are so inclined I would love it if people would post a link to this blog in the comments of the above youtube video. Perhaps we can get a discussion going and deepen everyone’s understanding of this issue.

The Relationship between the Catholic Church and Science

Go through what you know about the title.  What comes to mind?

Did anyone think of Galileo?

For many people Galileo seems two epitomize the relationship.   But to say that turns history on its head.   Science was born in a deeply Christian culture.   As I indicated I recently finished some books by Rodney Stark and I also just finished a book by James Hannam called the Genesis of Science. (Painting a basement is always a good time to listen to some audible books)  I have to say I am simply amazed at how much of science  middle age “natural philosophers” put together before even Copernicus came on the scene.

The importance of applying math to nature, using empirical evidence to test theories, including but not limited to, how objects move, how light works, whether the earth moves, how things might work in a vacuum etc.   Why was I so ignorant of all this?   I can tell you it’s not that I was taught all this and forgot it.  All of these great medieval thinkers were left out of my education.  None of it quite fit the “scientific revolution” view of history.  You know the story where the Catholic Church had to let the poor scientists out of their evil clutches before science could advance.      If you read Hannam’s book you will see that the Catholic Church and the university system (which was heavily fostered and influenced by the Church) was actually the major force that brought about science.

So what are the facts about Christianity and Science?  For that I highly recommend Hamman’s book to get a fuller picture.   Honestly it was such a flood of new and interesting information I do not have the perspective to summarize it properly. (I offer some other blogs below that do that.)

But here I will just offer something from Rodney Stark.  Rodney Stark is what I consider a hard working scholar.  He tends to do the nitty gritty work of looking up facts and delivering the information.  He did the legwork and looked up the all the major scientists during the “scientific revolution” and addressed how religious/Christian they were.  Here is his explanation of his methodology:

“Historians typically define the era of the “Scientific Revolution” as stretching from the publication in 1543 of Copernicus’s De revolutionibus to the end of the seventeenth century. Therefore, I selected Copernicus as my first case and included all appropriate cases, beginning with Copernicus’s contemporaries and stopping with scientists born after 1680. The “whom” was a bit more difficult. First of all, I limited the set to active scientists, thus excluding some well-known philosophers and supporters of science such as Francis Bacon, Joseph Scaliger, and Diego de Zuniga. Second, I tried to pick only those who made significant contributions. To select the cases, I searched books and articles on the history of science, and I also consulted a number of specialized encyclopedias and biographical dictionaries, among which I must mention the several editions of Isaac Asimov’s Biographical Encyclopedia of Science and Technology for its completeness and lack of obvious biases. Having developed a list of 52 scientists, I then consulted various sources, including individual biographies, to determine the facts that I wished to code for each case”

Christianity and Science from Stark (2003) For the Glory of God p.22

https://www.humanscience.org/docs/Stark%20(2003)%20Ch.2%20For%20the%20Glory%20of%20God.pdf

Stark put the 52 scientists in 1 of 4 categories.  Clergy, devout, conventional Christian, or skeptic.   “Devout” meant that they did things that demonstrated an unusual commitment to Christianity such as writing extensively on Christianity or other works indicating strong commitment to the faith.  “Conventional Christians” would be those who did not appear to be much more than typical Christians of the time.  He gives some explanations of how he grouped these people but in general he appears to have underestimated the religiosity.  For example a scientist who became the Popes physician was categorized not as devout but just as “conventionally” religious.

Here were the results:

13 (25%) were clergy 9 of them catholic clergy,  60% were devout. There were only 2 who were skeptics.

Now yes it’s true that people in Europe at this time tended to be Christian.   But that raises the question:   Of all the places and times, was it coincidence that Science developed in Christian society?  Not in the Roman Empire, not in China, Not in Islamic cultures or Persia.  Not in any of the other times and places.    Rodney Stark and others think that is not just a coincidence.  For example, early on Christians have been open to the idea that our senses can be reliable guides to reality.  (Unlike certain Greeks that taught how the material world was relatively unreliable)    Moreover, Christians put a high value on logical thinking and reason in theology.   Christianity is an intellectual religion which made science (then known as natural philosophy) and mathematics required courses in its medieval universities.    People who argue there is a conflict between Christianity and Science are taking the rare exception and calling it the rule.

Indeed, Galileo may be the only scientist who was ever persecuted by the church for his scientific view.    And those who are aware of Galileo case can legitimately question whether it was really his views as opposed to essentially calling the pope a simpleton which lead to his persecution.  Feel free to read more on the story for youself and draw your own conclusions.   Based on what I have read I do find the Church blameworthy in that case, even if Galileo was a stubborn, egocentric, and abrasive genius.

Remaining ignorant of all the people who lead up to Galileo and Copernicus in order to push the “enlightment” myth was a sad state for educational institutions.  But there is hope this prejudice is being scraped away thanks to scholarly work.  Not only has Hamman’s work received acclaim but I am told scholars are viewing his books and their views as relatively uncontroversial – at least to those who study this matter.

Short of reading Hamman’s book I would invite those with an interest in the history of science to take a look at this blog by Tim O’neill where he reviews God’s Philosophers: How the Medieval World Laid the Foundations of Modern Science By James Hannam:

http://armariummagnus.blogspot.com/2009/10/gods-philosophers-how-medieval-world.html

Although he is himself an atheist bastard, he also has a blog that debunks much of “new atheist” history here:

http://historyforatheists.blogspot.com/

As people who are interested in truth we should read about history and where we see the ignorant prejudices of the past being propagated, suggest the person at least read some of the above listed books or blogs.

Bearing False Witness – Book Review

17 Monday Oct 2016

Posted by in atheism, Athesism Christianity, Catholic, history, Morality, philosophy, rationality, science, Uncategorized

≈ 3 Comments

I just finished listening to three books by Rodney Stark, Bearing False Witness, Triumph of Faith, and How the West Won.  Here is just a brief review of the first book.

 

In Bearing False Witness, he describes how he believes the Catholic Church has received unwarranted attacks over the centuries.   As a History buff of medieval Europe and the middle east I have come to draw similar conclusions on a variety of topics.  But this book has that as the central thesis, therefore he marshals the facts for more coherent case.

 

Stark puts it all together with his central thesis in mind and does so in an informative way.  He covers different issues with a broad brush.  These include the Church’s interaction concerning Nazism, the Crusades, the bible’s formation, treatment of other religions including Judaism, the inquisition, slavery, science, and tyrannical governments. Since he covers the issues in a relatively broad brush the book is an easy read/listen.

 

The topics included some information that I already learned from other sources as well as new information.  I found that when he covered a topic I already had background information on, he was fair in his treatment.   That’s not to say he took pains to present every possible counter example, but on the whole he was fair.

 

He opens with a question the question why bother trying to defend the church and dredge through all this history?     It’s a question I asked myself in a prior blog.  But whereas I could not formulate a decent answer, he did by quoting Garrett Mattingly “Nor does it matter at all to the dead whether they receive justice at the hands of succeeding generations. But to the living, to do justice, however belatedly, should matter.”

 

I really enjoyed the chapter concerning science.   The basic construct of scientific method had already been put together by various monks and religious people in the middle ages.   Later scientists who are often credited as being the fathers of science were putting those principles into use on a very large and impressive scale.   I was quite impressed with the quotations from the scholastics which formed the bedrock of scientific method.

One interesting theory he suggested, was that science did not so much need to fight religion as much as it did the Platonic view that empirical information was not as valid as a-priori ideas.

In the end if you think you will learn the Church always acted just like we do now with our modern sensibilities, you will be disappointed.  However, if you would be satisfied with a strong case that the Church has been a huge force of progress, in science, education and morality then I think this book is for you.

 

How Abstract Concepts can be Real

I have noticed when I talk about abstract concepts such as morality and ask for evidence of them, I am being unclear to some. I don’t mean that morality is a physical thing somewhere that we can find like a moon orbiting Saturn. But I do mean it is real.

If I say I am taller than my daughter I am invoking an abstract concept – tallness. If I say prove tallness “exists in reality” (or provide evidence that tallness exists in reality) as opposed to our minds that might mean different things to different people. Some people would think I mean we must find an actual platonic-like form of tallness that is perfectly tall. That is not what I mean at all.

I think I “really” am taller than my daughter. That is in reality I am taller. The notion of tallness is something like, when I am standing, the highest part of my body is higher than hers (when she is standing) means I am taller than her. This tie in with reality makes the notion that I am taller than my daughter objectively true. It’s not just that I believe it is true. My belief does not make the statement true or false. Reality makes that statement true or false. That is because tallness has a tie in with reality.

Does morality have tie in with reality? If I believe something is wrong does my belief make it wrong? Or does reality determine whether my belief is true or false. The latter is what I mean when I say morality is objectively real. It is not the case that I necessarily think there is some perfectly moral good form (or perfectly evil form) somewhere that we need to find. What I am asking is 1) whether these concepts have a tie in with reality. And 2) if so, how we would know in what ways morality ties in with reality.

I think I answered the first question with respect to tallness. Yes tallness ties in with reality so we can say it is really and objectively true that I am taller than my daughter. What about the second question with respect to tallness? I think we have empirical evidence that I am really taller than my daughter. We can see me standing next to her. Even a blind person would be able to feel if we are standing, and then feel the top of my head relative to the top of her head. So we have empirical evidence of how “tallness” ties in with reality.

But what about “wrongness”? Here it seems we do not have empirical evidence.

Sure we can substitute concepts for “right and wrong” and “good and evil” and then assert that this new word is promoted by such and such conduct. But whenever I see this one of 2 things is always happening. Either they are leaving the new term so vague that it is pretty much vacuous, and thus the “definition” is vacuous. (that which makes us “thrive” or that which brings “happiness” etc.) Or they do in fact put some constraints on the definition and then I have to wonder if that is really good. I gave a hypothetical that approaches one of the latter views here: https://trueandreasonable.co/2014/12/19/a-moral-hypothetical/

In any case, I do think we can have empirical evidence of abstract ideas.  But in the case of morality the the evidence of morality is the evidence for God.  I talk more about that connection here:

Evidence of Objective Moral Realism

A fellow blogger and sometime commentator here, Howie, asks some questions for theists.

https://truthiselusive.wordpress.com/2016/04/22/meaningful-sadness/

He wonders what effect would it have on our morals if we suddenly found out God did not exist.  It’s a great question and I found I could spend allot of time answering this.

 

In my response I indicate that “I would highly doubt any objective morality exists in reality, and if it did exist I would not believe we had any reliable way of knowing what it was.”

 

I have blogged extensively about the second part of that statement:

https://trueandreasonable.co/2014/02/24/a-problem-with-the-reliability-of-moral-beliefs/

Here I want to address the first part.  I want to explain why “I would I highly doubt any objective morality exists in reality” if I found out God did not exist.

 

But first, I want to reiterate that I do not think there is any logical inconsistency with atheism and belief in objective morality.   That said I am unaware of any actual evidence that an atheist would have for believing in objective morality.    That is, if we were to know there is no God then all the evidence we have for objective morality goes out the window.   It’s one thing to say objective morality is logically possible, it’s another to say we have some evidence that it is true.

 

To understand my position let’s start with a reverse question for atheists.   Let’s say you suddenly find out that the Christian God exists.  What would that mean for your views on morality?

 

I would think most people would agree that if the Christian God exists, then it’s very likely that objective moral realism is true.    God orchestrated our existence and reality so that we might be ultimately judged and this judgment will be just.  Reality would have been built with this moral feature.

 

From that, it follows that evidence that the Christian creator God exists is also evidence that objective morality is a feature of reality.   The evidence that the Christian God exists would be things like the miracles recorded in scripture.  Again people can debate whether this is strong evidence or weak evidence, and what if any burden of proof there is, but it is “some evidence.”  This also happens to be the only evidence that our objective reality contains moral characteristics. (I don’t mean to exclude other religions that teach of a Creator God who had a hand in creating a moral reality.  So yes evidence for Islam, or Judaism would also be evidence for objective moral realism but here for simplicity sake I am just taking Christianity versus atheism.)   So the logic is exhibit A suggest exhibit B.  Exhibit B Suggests exhibit C.  A = miracles B=Christian God exists and C = Objective moral realism is true.

 

Do we have other evidence that objective morals are actually a feature of reality?  I really don’t think so.  Again because “wrongness” cannot be detected by our 5 senses it seems impossible to have evidence of it outside of testimonial evidence from someone who is not bound by our 5 senses.

 

The fact that we feel strong guttural emotional responses when we see certain “good” or “bad” actions is not, to my mind, evidence that there is actually a real objective truth to moral claims.  However, if something with a supernatural understanding designed us then of course we might think our emotions are properly cued to these real moral truths.

 

So the Christian God existing would be strong evidence that real objective morals would exist.  If we were to eliminate that evidence of objective moral reality existing (Say because we “find out” no God exists) then we are hard pressed to find *any* evidence of objective moral reality.   That’s not to say its logically impossible for objective moral reality to exist without God.  Nonetheless, it would be a huge blow to objective moral realism’s case to lose – exhibit B – the existence of God.
